Things to Do in Nagoya: Castles, Cars, and Cuisine

Nagoya is a hub of Japanese innovation and history, offering highlights like the historic Nagoya Castle, the world-class Toyota museums, and a unique local food scene featuring miso-katsu and hitsumabushi. It is the perfect stop between Tokyo and Kyoto for travelers who want to see Japan’s industrial prowess and traditional soul without the massive crowds. Whether you are a car enthusiast, a history buff, or a foodie, Nagoya has a distinct vibe that sets it apart from the neon-soaked streets of Shinjuku or the ancient temples of Gion.

For Australians and Kiwis making the trek over, Nagoya is often the 'underdog' city that ends up being a trip highlight. But before you start hunting for the best chicken wings in the city, you need to sort your connectivity. Don't be the person who lands at Chubu Centrair International Airport only to realize they are being slugged $10 a day by the Telstra International Day Pass or similar daily roaming charges from Optus and Vodafone. Those costs add up faster than a Shinkansen ride. Instead, you can grab an AussieRoam eSIM and land with data ready to go.

Why Nagoya Deserves a Spot on Your Itinerary

Nagoya is the capital of Aichi Prefecture and the fourth-most populous city in Japan. It’s the birthplace of Toyota, which means the city is wealthy, clean, and incredibly efficient. While Tokyo can feel overwhelming and Kyoto can feel like a tourist museum, Nagoya feels like a real, working Japanese city with a massive heart.

One of the best things about Nagoya is its location. It sits right on the Tokaido Shinkansen line. If you are using our guide on how to travel Japan on a budget, you’ll know that strategic stops can save you a fortune in transit time and accommodation. Nagoya is often cheaper for hotels than Tokyo, making it a great base for exploring central Japan.

Top Things to Do in Nagoya

1. Explore Nagoya Castle

Originally built in the early 17th century, Nagoya Castle is the city's most iconic landmark. While the main keep is currently closed for earthquake reinforcement, the Honmaru Goten Palace is a masterpiece of Japanese architecture. The interior is covered in gold leaf and intricate paintings that will blow your mind. Keep an eye out for the Kinshachi—the mythical golden tiger-headed carp that adorn the roof.

2. Dive into Car Culture at the Toyota Museums

Nagoya and car culture go hand in hand. There are actually two major Toyota sites. The Toyota Commemorative Museum of Industry and Technology is located in the city and tracks the company's history from a textile machinery manufacturer to an automotive giant. If you want to see the actual cars, head out to the Toyota Automobile Museum, which houses a massive collection of vintage vehicles from all over the world.

3. Get Your Geek On at SCMAGLEV and Railway Park

Even if you aren't a train spotter, this place is impressive. It showcases the history of the high-speed rail in Japan, including the world-record-breaking Maglev trains. You can walk through old steam locomotives and see the evolution of the Shinkansen. It’s interactive, sleek, and very 'Nagoya.'

4. Shop and Snack in Osu Kannon

Osu Kannon is a funky district centered around a large Buddhist temple. The surrounding covered shopping arcades (shotengai) are a mix of traditional craft shops, electronics, vintage clothing, and incredible street food. It’s less polished than Tokyo’s Ginza, which is exactly why we love it. This is the place to try Gohei-mochi (grilled rice cakes with miso).

The Cuisine: Why Nagoya-meshi is Different

Nagoya’s food scene, known as Nagoya-meshi, is famous for its bold, rich flavors, largely thanks to the local obsession with akamiso (red miso). Here is what you cannot miss:

• Hitsumabushi: Grilled eel (unagi) served over rice. There is a specific way to eat it: first plain, second with condiments (wasabi and nori), and third with a savory dashi broth poured over it.
• Miso-katsu: A deep-fried pork cutlet smothered in a thick, sweet, and savory red miso sauce. It’s heavy, delicious, and the ultimate comfort food.
• Tebasaki: Nagoya-style chicken wings. They are seasoned with a peppery glaze and are the perfect accompaniment to a cold Japanese beer. Check out the famous chain Sekai no Yamachan for the authentic experience.
• Kishimen: Flat, broad wheat noodles served in a tasty broth. They are smoother than standard udon and a local staple.

Staying Connected: AussieRoam vs. Roaming

Navigating Nagoya’s subway system or finding that hidden eel restaurant in Osu Kannon requires reliable data. Relying on public Wi-Fi in Japan is a recipe for frustration—it’s often slow and requires a complex login process.

If you stick with your Australian or NZ home carrier, you might be looking at $5 to $10 per day for a tiny sliver of data. AussieRoam offers Japan eSIMs that run on the best local networks: NTT docomo (5G), Rakuten Mobile (5G), KDDI/au (5G), and SoftBank (5G). This means you get the same coverage as the locals, whether you are in the basement of Nagoya Station or hiking in the nearby mountains of Gifu.

Comparison Table: AussieRoam vs. Traditional Roaming

Feature	AussieRoam Japan eSIM	Telstra/Optus Roaming
Network Access	Docomo, Rakuten, KDDI, SoftBank (5G)	Usually restricted to one partner
Daily Cost	One-off fixed price	$5 - $10 per day
Data Limit	Flexible (up to 50GB)	Often capped at 1GB/day
Setup	Digital QR Code	Automatic (expensive)
Local Number	No (Data only)	Yes (using your AU/NZ number)

Our plans are data-only, which means you won't get a local Japanese phone number. However, in 2026, who needs one? You can still use WhatsApp, Messenger, and FaceTime for all your calls and texts. Check out our Japan see plans to find the right fit for your trip duration.

How Much Data Do You Actually Need?

Not sure which plan to pick? Here is a rough guide for a typical traveler in Nagoya:

• Google Maps: Essential for navigating the Meitetsu and JR lines. Uses about 5-10MB per hour of active use.
• Social Media (Instagram/TikTok): This is the data killer. Uploading high-res reels of your miso-katsu can burn through 500MB in no time.
• Google Translate: Using the camera feature to read menus is a lifesaver. This uses minimal data but is much faster on a 5G connection.
• WhatsApp Calls: Uses about 1MB per minute.

If you are a light user, a 3GB or 5GB plan for 15-30 days might be enough. If you are constantly posting to your story, consider our 10GB or 20GB options. We even have daily passes like 1GB or 2GB per day if you prefer a 'set and forget' approach. You can see plans here and choose what works for your style.

How to Install Your eSIM

You don't need to find a kiosk at the airport or fiddle with paperclips and tiny plastic SIM cards. Before you head to the airport in Sydney, Melbourne, or Auckland, check your phone’s compatibility to ensure it supports eSIM technology. Once you're sorted, the process is simple.

For iPhone Users:

1. Open Settings > Cellular.
2. Tap Add eSIM.
3. Scan the QR code provided by AussieRoam in your email.
4. Label the new plan as 'Travel' or 'Japan'.
5. Set your 'Cellular Data' to the new eSIM but keep your 'Primary' line for calls/SMS (if you want to keep your home number active—just turn off Data Roaming on your Primary line!).

For Android Users:

1. Go to Settings > Connections.
2. Tap SIM manager.
3. Select Add eSIM or Add mobile plan.
4. Scan the QR code.
5. Ensure the AussieRoam eSIM is selected for mobile data once you land in Japan.

Getting Around Nagoya

Nagoya is incredibly well-connected. The Nagoya Subway has six lines that cover most of the city center. For the car museums and SCMAGLEV park, you’ll likely use the Linimo (a magnetic levitation train!) or the Aonami Line.

If you are arriving from Tokyo or Osaka, you'll land at Nagoya Station (Meieki), which is one of the world's largest train stations. It can be a maze, so having a live Google Maps connection is vital to avoid getting lost in the underground shopping malls.

The bottom line

Nagoya is a city of surprises. It offers a perfect blend of industrial might and traditional charm without the exhausting crowds of Japan’s other major cities. By grabbing an AussieRoam eSIM before you fly, you can skip the overpriced roaming fees and spend that extra cash on a second round of Nagoya’s famous chicken wings. Land, tap, and start exploring the heart of Japan with total confidence.
